c) Spannungsmessung „V“
Zur Messung von Gleichspannungen „V “ (DC) gehen Sie wie folgt vor:
- Schalten Sie das DMM ein und wählen die Messfunktion
„V “. Im Display erscheint „DC“ und die Einheit „V“.
- Für kleine Spannungen bis max. 600 mV wählen Sie die
Messfunktion „mV “.
- Stecken Sie die rote Messleitung in die V-Messbuchse (G), die
schwarze Messleitung in die COM-Messbuchse (H).
- Verbinden Sie die beiden Messspitzen mit dem Messobjekt
(Batterie, Schaltung usw.). Die rote Messspitze entspricht dem
Pluspol, die schwarze Messspitze dem Minuspol.
- Die jeweilige Polarität des Messwertes wird zusammen mit
dem augenblicklichen Messwert im Display angezeigt.
- Entfernen Sie nach Messende die Messleitungen vom Mess-
objekt und schalten Sie das DMM aus.
Sobald bei der Gleichspannung ein Minus „-“ vor dem Messwert erscheint, ist die gemessene Spannung
negativ (oder die Messleitungen sind vertauscht).
